IMPROVEMENT IN HEATING APPARATUS.

Specification forming part of Letters Patent No. 195,320, datedSeptember 18. 1877; application filed May 12, 1877.

To all whom it may concern:

Be it known that I, ALVIN T. WINOHELL, of Albion, in the county ofCalhoun and State of Michigan, have invented a new and valuableImprovement in Heating Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of @he same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawing is a representation of a side elevation of myinvention. Fig. 2 is a similar view, with a portion of the chamber insection. Fig. 3 is an end view.

This invention has relation to heating apparatus; andthe object andpurpose thereof are to construct a device by which the escaping heatcontained in the smoke may be used for heating the cold air, which, whenthus heated, may be used for heating, warming, or evaporating purposes,the arrangement and construction of the several parts of the apparatusbeing herein after described, and subsequently pointed out in the claim.

In the accompanying drawings, A represents a chamber of any suitableform, which may be made of metal or other suitable material, such asbrick or clay, as circumstances may require. The chamber A has asuitable number of flues, B, for the passage of cold air, which are madetapering to cause a draft of the smoke within its chamber from thelarger to the smaller end of the flues B, this tapering form alsoadmitting of the ready removal of the fines when required for cleaning,repairing, or for other purposes.

chamber A also has inlet and outlet pipes O D for the smoke.

It will be seen that, as the cold-air fines are surrounded by the heatedsmoke as it passes into the chamber, the air in the dues will becomeheated during its passage through them, and the air thus heated may beconducted to any desired point, each flue being independent of theother, thereby allowing the hot air to be conveyed to difi'erentapartments; or they may be connected together according to the amount ofheat required.

The flues, as will be noticed, are placed in sections, one above theother horizontally, and with their ends reversed alternately, whicharrangement. together with the tapering form of the flues, will cause areturn draft of the smoke within its chamber, which draft will have afree passage through and between the air-flues at their smaller ends,causing the smoke to pass from the larger to the smaller end of theflues between the sections thereof, whereby a smoke flue is formedwithin the chamber, which at its bottom is largest at the inlet end, andat its top is smallest at its outlet end, producing a zigzag current.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

The chamber A, having pipes U D and removable tapering flues B, arrangedin sections, one above the other, with their ends reversed alternately,as shown, whereby a smoke-flue is formed within the chamber, which atits bottom is largest at its inlet end, and at its top is smallest atits outlet end, producing a zigzag current, substantially as and for thepurposes set forth.

In testimony that I claim the above 1 have hereunto subscribed my namein the presence of two witnesses.

ALVIN T, WINOHELL.
